[0025] Please see Figures 1-5In this embodiment of the invention, a swimming goggle lifespan testing device includes: a sealed test chamber 1 with a base 11 installed below it. Rotatable rollers are provided at the four corners of the lower end face of the base 11. Two test chambers are provided on the left and right sides of the sealed test chamber 1. Each test chamber has a positioning column 12 on which a swimming goggle to be tested is mounted. A sand-feeding and drainage mechanism 2 is provided outside each test chamber, forming a circulation loop with the test chamber for circulating sand-containing water. A pressure-applying component 3 is provided at each positioning column on the sealed test chamber 1. The pressure-applying component 3 contacts the swimming goggle to be tested and performs a lifespan test. The positioning column can be a human face model. During the goggle test, it is observed whether the goggle leaves an imprint on the human face model when it comes into contact with it, and the presence of water leakage is also tested.

[0026] In this embodiment, the sand delivery and drainage mechanism 2 includes: a circulation pipe 21 with a C-shaped cross-section, the two ends of the circulation pipe 21 being connected to both sides of the test chamber, a mud pump 22 connected in series on the circulation pipe 21, a ring seat 24 embedded and fixed in the test chamber, a shaft tube 25 rotatably disposed within the ring seat 24, one end of the shaft tube 25 being rotatably connected to the circulation pipe 21, a guide vane 27 fixed on the shaft tube 25, and an external motor 26 installed on one side of the sealed test box 1. The output end of the external motor 26 is connected to the shaft tube 25 through gear meshing; thereby, the guide vane guides the flow of sand-containing water inside, causing it to impact the swimming goggles.

[0027] The test chamber is provided with rotatable inner turbines 23 symmetrically arranged on the side away from the ring seat 24.

[0028] A cylinder seat is also connected in series on the circulation pipe 21, and multiple sand supply pipes 4 are arranged inside the cylinder seat.

[0029] In a preferred embodiment, the sand supply pipe 4 is constructed as a double-sided pipe structure, and its inner pipe wall has multiple sand holes 42 distributed circumferentially. The sand supply pipe 4 is connected to a transfer pipe 41 for transporting sand-containing water. A baffle plate 43 is embedded and fixed on one side of the sand supply pipe 4. An inner ring sleeve 45 is coaxially rotatably arranged on the sand supply pipe 4. An adjusting plate 44 is fixed on the inner ring sleeve 45. The adjusting plate 44 abuts against the baffle plate 43. Multiple flow holes are opened on both the adjusting plate 44 and the baffle plate 43. A guide tube 46 is fixed on the side of the sand supply pipe 4 near the inner ring sleeve 45.

[0030] In this embodiment, multiple sand supply pipes 4 transport sand-containing water with sand particles of different sizes through transfer pipes 41. The flow holes on the regulating plate 44 can be offset from the flow holes on the baffle plate 43 as the inner ring sleeve 45 rotates. That is to say, during the test, the transfer pipe 41 on one side of the sand supply pipe 4 can continuously transport sand-containing water and stop after the water volume reaches the capacity standard. At this time, the sand-containing water is circulated and transported by a mud pump. During the transport, the regulating plate 44 forms a filtering effect on the sand particles in the sand-containing water as the inner ring sleeve 45 rotates, thereby facilitating the control of the impact and wear intensity of the sand-containing water on the swimming goggles and simulating the service life of the swimming goggles under different usage environments.

[0031] In this embodiment, the pressure application component 3 includes: a positioning plate 31, which is horizontally suspended above the sealing test chamber 1. Two connecting rods 32 are vertically slidably arranged on the positioning plate 31. One end of the connecting rod 32 is slidably connected to the sealing test chamber 1. A pressure plate 33 is horizontally arranged below the connecting rod 32. A hydraulic cylinder 34 is vertically fixed on the positioning plate 31. The telescopic end of the hydraulic cylinder 34 slides through the pressure plate 33, and a center seat 35 is fixed at its end. Locking rod frames are symmetrically hinged on the center seat 35. A deformation guide 5 is clamped outside the swimming goggle to be tested. The other end of the locking rod frame is connected to the deformation guide 5.

[0032] A side rod 36 is symmetrically connected below the pressure plate 33. One end of the side rod 36 is connected to the locking rod frame. When the hydraulic cylinder continues to contract, the deformation guide 5 can retract under the rotation of the locking rod frame, thereby forming a high-intensity pressure deformation on the swimming goggles.

[0033] In this embodiment, a linear oscillator 37 is vertically connected between each of the connecting rods 32 and the pressure plate 33. In particular, during the test, the linear oscillator 37 can drive the pressure plate to continuously move under synchronous high-frequency vibration output. At this time, the pressure plate can apply pressure at the same frequency by controlling the deformation guide through the side rod, thereby realizing the fatigue test of the swimming goggles.

[0034] In this embodiment, the deformation guide 5 includes: a cross frame 51, on both sides of which sliding members 52 are slidably arranged; a locking rod frame is rotatably connected to the sliding members 52; an elastic frame plate 53 is connected between the sliding members 52; the cross-section of the elastic frame plate 53 is arc-shaped; a linkage rod 55 is rotatably connected to the middle of the elastic frame plate 53; the linkage rod 55 is connected to the middle of the swimming goggles under test through a clamp 54; that is, the sliding members on both sides can form a squeezing effect on the swimming goggles under displacement drive, thereby simulating the deformation during high-frequency use and wearing, and thus testing the wear life of the swimming goggles.

[0035] In this embodiment, the positioning column 12 is provided with an inflatable airbag at the protective frame of the swimming goggles to be tested. On the one hand, it can simulate the sealing test during the use of swimming goggles, and on the other hand, it can assist the deformation of the main body of the swimming goggles to simulate the degree of deformation of the swimming goggles when worn by a human face.

[0036] Specifically, in the comparative test, two swimming goggles of different specifications can be placed in each test chamber and their lifespan is tested by the sand delivery and drainage mechanism and the pressure application component to form comparative data; while in the combined test, the swimming goggles are subjected to different intensity use tests in two test chambers to simulate the deformation recovery and sealing performance of the swimming goggles during intermittent use, or the lifespan of the swimming goggles under proper maintenance, with high data reliability.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
